First, image. The proper use of reduplicated words in poetry can make the depicted natural scenery or characters more vivid. The first six sentences of "grass on the green side" in Nineteen Ancient Poems use six overlapping words: "grass on the green side, willow in the shady garden. Ying Ying is a woman upstairs with a bright window. Moths make up with red powder and have slender hands. " The last four sentences are about people, and the four groups of overlapping words describe Sifu's posture, appearance and dress very vividly, almost vividly.
Second, accuracy. Overlap can imitate sound and color to achieve the rhetorical effect of description and make the image expressed more accurate. For example, "Ancient Poetry is Jiao Zhongqing's Wife" "The official horse is in front, the bride's car is behind, and there is a faint and hall. It is very accurate to imitate the sound of horses and chariots with" faint "and" hall "and render the repatriation of Lan Zhi." In Du Fu's Ascending the Mountain, "leaves fall like the spray of a waterfall" uses "rustling" to imitate the sound of fallen leaves; In Huang Chao's title chrysanthemum, "autumn wind plants all over the courtyard", imitating the wind with "rustling"; In Yue Fei's "Man Jiang Hong", the word "Mao Mao Rain" is used to imitate the sound of rain ... When the marriage is arranged, it is written: "When the matchmaker gets up, Nuo Nuo will recover. Here, "Nuo Nuo" and "two" are promises, which are equivalent to "good, good" and "just like this" in modern Chinese.
Third, musicality. Reduplication can make poetry rhythm harmonious and catchy to read; That sounds very pleasant. For example, Li Bai's "The Tenth of the Seventeen Qiupu Songs": "Qian Qian Heather Tree, a Thousand Li Privet Forest, Egrets all over the Mountain, and White Apes all over the River. You don't want to go to Qiupu, the ape sound hurts the guest. " The first four sentences of the poem are led out by overlapping words, which are lively and full of musical beauty.
Fourth, strengthen. Reduplication is easier to read and plays an emphasis role.
